DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column / beam joint structure and a column / beam frame structure in a laminated wood structure, wherein a rigid frame structure is constituted by columns and beams of the laminated wood.

[0002]

2. Description of the Related Art Since joints between wooden columns and beams using glulam are generally pin joints, basically use seismic elements such as braces and wall panels. Holds structurally. Recently, it has become possible to assemble a frame with a rigid frame structure by using a large-section laminated wood and combining curved metal members with hardware so that a frame with a rigid frame structure can be assembled. Is either a single-story, mountain-shaped frame structure or, in the case of a multi-storey floor, a frame structure with seismic elements, and there is no single-story frame with no multi-story elements.

[0003] The present invention has been made in view of the current state of laminated timber frames, and it is an object of the present invention to newly propose a joint structure that enables a pure ramen frame and a column / beam frame using the same.

[0004]

According to the present invention, a laminated timber beam is provided.
Cut off the end located at the joint with the glued lumber column, assemble this end member orthogonally, sandwich this with the glued lumber column divided into a plurality of through pillars and tube columns, and penetrate the glued lumber column, The joints of the columns and beams are rigidly joined by bolting them together, enabling the assembly of a frame with a pure ramen structure.

[0005] The laminated wood pillars are in contact with the corners of the end member, penetrate the joint in the height direction, and hit the lower end face and the top end face of the end member, and are sandwiched between adjacent through pillars. It is composed of at least four pillars on each of the floor side and the lower floor side.

[0006] The end member is sandwiched from the top and bottom of the through pillar of the laminated wood pillar from the side, from the top and bottom, penetrates in the beam width direction, and is joined to the laminated wood pillar by tightening a bolt inserted between the through pillars.

[0007] The end member of the glued laminated beam is sandwiched between the glued laminated pillar in the horizontal direction and the vertical direction. At the same time, the glued laminated pillar is tightened by a bolt penetrating in the beam width direction. And the transmission of the tensile force acting on the end member to the glued laminated wood column is ensured, the connection between the end member and the glued laminated wood column becomes rigid, and the frame of the column and beam has a pure rigid frame structure.

[0008] The column / beam frame is constructed by connecting a glulam beam between end members of a glulam beam joined to an adjacent glulam beam column and connecting to the end members.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing one embodiment.

As shown in FIG. 1, the invention according to claim 1 is located at the joint of the glued laminated wood beam 1 with the glued laminated wood pillar 3 and penetrates the orthogonally assembled end member 2 through the glued laminated wood pillar 3. And rigidly joined to it.

As shown in FIG. 7, the end member 2 is formed by, for example, laminating a plurality of plate members 21 in which laminas 20 orthogonal to one-way laminas 20 are joined together by joining the laminas 20 on the winning side alternately. They are laminated and assembled into a cross-shaped planar shape. After assembling the end member 2, the laminated timber pillar 3, which will be described later,
As shown in FIG. 5, which is a cross-sectional view taken along the line y-y of FIG. 3, a bolt insertion hole 22 is formed through the widthwise direction at the insertion position of the joining bolt 4 with the bolt.

As shown in FIGS. 1 and 2, the laminated wood pillars 3 are in contact with the corners of the end member 2 in two directions and penetrate the joint in the height direction. FIG. 4 is a cross-sectional view taken along a line xx of FIG. 3 on a plane from at least four pipe columns 32 on the upper floor side and the lower floor side, respectively, which abut against a lower end face or a top end face and are sandwiched between adjacent through pillars 31; As shown in FIG.
It is composed of books or nine pillars. In the embodiment shown in the drawing, since the tube column 32 is arranged at the center on the plane of the end member 2, the tube member is composed of nine column members on the plane, but the tube column 32 at the center is not arranged. In the case, it is composed of eight pillars. The through pillars 31 are provided, for example, from the middle part of the laminated wood pillar 3 on the lower floor side to the middle part of the laminated wood pillar 3 on the upper floor side, and are connected to each other at this middle part and continue in the axial direction. The tubular column 32 is installed from the top end of the glued laminated timber beam 1 on the lower floor side to the lower end surface of the glued laminated timber beam 1 on the upper floor side, and is joined to the through pillar 31 to sandwich the end member 2 from above and below.

As shown in FIG. 6 which is a sectional view taken along the line zz in FIG.
Bolts 4 that are inserted between 31 in the column direction and are arranged in two directions
When the nut 5 is tightened, the laminated wood pillar 3 is integrated. As shown in FIG. 2 and FIG.
In advance, the bolt insertion holes 311, 32
1 is dawned.

The end member 2 is sandwiched in the width direction and the height direction by the through columns 31, 31 and the tube columns 32, 32 as shown in FIG. 5, which is a sectional view taken along the line y--y of FIGS. Direction, and is joined to the laminated timber column 3 by bolts 4, 4 inserted between the through columns 31, 31 in two directions.

The end member 2 is, as shown in FIG.
The pipe column 32 on the upper floor side is installed from above and is connected to the through column 31, so that it is sandwiched between the through columns 31, 31 from the side, and the tube columns 32, 32 from above and below. It is. Furthermore, the nut 5 is tightened by a bolt 4 that penetrates in the beam width direction and is inserted between the through columns 31, 31, thereby being restrained against rotation about a horizontal axis, and rigidly joined to the laminated wood column 3. The tensile force acting on the upper end and the lower end of the end member 2 is transmitted from the through column 31 on the working side to the through column 31 on the opposite side by the tubular column 32, and the bending moment can be transmitted from the laminated beam 1 to the laminated column 3. Become.

According to a second aspect of the present invention, as shown in FIGS. 8 and 9, a laminated wood beam 1 is erected between end members 2 and 2 rigidly joined to laminated wood columns 3 and 3. 2 and is composed of a glued laminated wood pillar 3 and a glued laminated wood beam 1.

The joint surface between the end member 2 and the glulam beam 1 is shown in FIG.
As shown in FIG. 8, for example, a support portion 23 that protrudes from the upper end side to the lower end side of the end member 2 and supports the glued laminated timber beam 1 is formed, and is formed in a phased joint shape, and the joint has relatively small stress. Because it is a location, the joining hardware 6 is passed to both sides and connected by bolt joining.

[0018]

The present invention is as described above. The end of the laminated timber beam located at the joint with the laminated timber column is cut off, the end members are assembled orthogonally, and this is assembled with a plurality of through columns. Glued lumber pillars are divided into tube columns, sandwiched from the side and top and bottom, penetrate the glued lumber pillars, and because both are bolted together, the end members are restrained by the glued lumber columns and the tensile force acting on the end members The transmission to the column is assured, the column and beam joints can be rigidly joined, and a frame with a pure ramen structure can be assembled.
